  • Mainframe Standards

    This is the first post in a series on IT standards. The focus of this post is a review of standards that were created through mainframe computing and others that were later adopted. Creating standards and adopting others is a strength of mainframe computing and an important aspect of its resilience and vigor.

    The Future of Application Development Methods

    This is the final post in a series on how applications are developed. The focus of this post is a review of some of the current thinking on how to develop applications. Some practitioners lobby to take a new look at waterfall. Others are looking beyond agile in an effort to overcome some of its shortcomings. For many, the thrust is to modify what we have and make it better. For them, continuous improvement is a way to lower risk going forward.

    Make Waterfall Better With Prototyping and Incremental

    This is the second post in a series on how applications are developed. The focus of this post is how prototyping and incremental methods work and why some say that they “do it better” than waterfall. You’ll be able to see that some of the shortfalls of waterfall are addressed through the use of these methods that can be used in conjunction with waterfall, not necessarily as a replacement.

    Cloud on the Mainframe Has Many Options

    This is the fourth and last post in a series on cloud conventions and innovations. In the previous post, I set the groundwork for cloud on mainframe by making a case that mainframes are an excellent place to host Linux images. Since cloud is more than Linux, in this post I will share more details on a mainframe-based cloud service.

    Linux on the Mainframe and Cloud

    This is the third post in a series on cloud conventions and innovations. In the first two posts, I discussed a number of attributes of cloud including quickness, cost and price, upkeep, shared use, ease of working, and scaling up and down. These attributes are used to boast about the benefits of cloud services but are also a key part of the value of mainframe computing.

    Cloud Services and Mainframe Computing

    This is the second post in a series on cloud conventions and innovations. As I discussed last week, some characteristics of cloud are simply conventions whereas other features are new and innovative. Many of the characteristics of cloud computing are like mainframe computing, as both utilize centralized computing technologies like virtualization and approaches like providing systemwide backup and database management.

    Cloud Is Old and New United

    This is the first post in a series on cloud conventions and innovations. Some characteristics of cloud are simply conventions—the way things are done—whereas other features are new and innovation. The difference and context for these contrasting characteristics and features is the subject of this series of posts.

    DevOps and Tools

    This is the last post in this brief two-part series on DevOps. DevOps was discussed in my previous posts on microservices so I explored it in this two-part series. In this post I survey some of the tools that align with DevOps to make it even more useful as a method to develop applications.
